    That looks pretty good just send the seller a question and ask. with a 4gb sd card you could get 10 hours of run time good luck.

    I have often contemplated something similar to this myself as an added security measure. The big problem is incorporating all of the desired functions into a single unit for a reasonable cost to the average consumer.

    1. The recording system should be capable of being in 'standby' when not used. Extended periods of time without driving the car while still providing protection would then be possible. (so a computer that could wake from hibernation or similar to immediately record from an input trigger)
    2. A simple micro field sensor designed for car alarms can be used to generate a trigger when any motion is detected. That means if anyone/anything gets close to the car the sensor will activate. The sensitivity can be adjusted with a small pot on most units.
    3. Long recording times to capture the most information when most critical.
    4. Low power consumption under normal operating conditions. Always think about the worst case scenario in devising your system. ie. you leave on vacation and the car sits at airport parking for a week. Several events trigger the recording over that week, so battery power has to be utilized.

    The proprietary system at that link has been designed with all these things in mind...except cost.

    An much cheaper solution would be to use the same micro field sensor output to trigger a dc vcr/dvr. With a timed relay you could rig the power to come on, then activate the record button. If only one camera is used it is simple, but if multiple cameras are used one more step is needed. Add a video multiplexer. Audiovox used to manufacture a dc model, but I think it has been discontinued.

    I searched for awhile for a vcr/dvr with the trigger input built-in but only found units designed to be used for home security systems. The size was bulky and so was the power consumption.

    The bottom line is this.
    If you want peace of mind get more insurance. Let the punks steal what they will no matter what security you have.
    If you are serious and competent with electronics, more power to you.

    I decided even the lower cost of the homebrew system and the time to put it together far outweighed the functionality for me.

    More power to you man!

    A simple system would be a DVR like this one and a IR camera like this.

    The DVR runs on 5v dc or batteries, camera and dvr are very small, it records on SD cards, has multi-zone motion detection trigger to preserve power, and has date/time overlay.

    Here's a thread in the GPS section where someone used a similar setup and added GPS overlay to provide car security.

    I don't care about them stealing my car I wish they would have just stolen it, what I care about is people vandalizing it, pouring acid on my car/brake fluid to eat away my paint, that's what I care about. I wish they would have just taken the car just for piece of mind, insurance won't total a car out for paint dmg. my car is worth more from insurance than what I paid and i have full coverage.

    The first part looks great but the camera, Runs on a 12V DC power supply @ 160mA. that running all the time wouldn't that kill my battery.

    Hi, i have been very curious abt car security with surveillance camera feature. Likewise, power is a main issue.

    After much thots, i do have a rough concept using ASUS EEEpc and a WIRED IP cam. So is a WIRED IP cam able to send Magic Packet when its motion detection activated and wake up the PC when the PC is in hibernation mode?

    The connection will be as follow.

    Wired IP Cam -> Crossed RJ45 cable -> PC LAN port.

    Is it workable?

    TIA!

    Is the camera going to be in the car? If so you might want to check your local laws. I have read that it's illegal to do that without putting notification on your car that there is a recording devise..... Gotta love the rights we give criminals here.

    yes of cos...

    the plan is to let the PC to go into hibernate mode, and only start recording once it is wake up by the IP camera's motion detection.
